在另一个PHP脚本中使用joomla accounting

Question

我有一个Joomla网站，里面有一个PHP脚本。有一个按钮可以将人重定向到PHP脚本。我想将我的Joomla站点用户组用作访问级别。那些不登录的人应该被阻止访问PHP脚本的 index.php 并收到一条消息，例如“你必须先登录！” / em>以及 登录的用户，可以访问PHP脚本的 index.php 。

我所做的是在PHP脚本的 index.php 的顶部包含Joomla框架并放置函数：JFactory::getUser();。之后，我将整个 index.php 置于if-else条件下。 if的条件是getUser()的返回值不等于“guest”。

else部分工作正常并显示消息“您必须先登录”，但if部分不起作用，只显示空白页面收到＃

error 500 "internal server error"

这意味着我的代码会识别已登录的内容以及未登录的代码。 此外，当我删除我的个人代码时，它会向所有人正确显示 index.php 。

帮帮我吧
